High pitch squeeling noise at 1500 rpm comes and goes when over 1500 or under 1500rpm

turbos normal make a whining noise under load noise may be present more then before if you have changed anything on the intake side sometimes it can be as little as a lest restricted air filter other cause is lose piping but some power loss would be noticeable if this was the cause
hope this helps good luck

you need to replce the cluch and preasure plate. the clutch is gone, its hard to shift because there is nothing left to pushout on the plate and the squeeling is from the same problem, the clutch works like brakes, when the pads are gone and you step on brake you get asqeeling sound from it being metal to metal the same thing is happening with your clutch

If your car has hydraulic tappets and low low oil pressure at engine speeds then it can make tapping noises. Oil pressure is needed to maintaine the tappets clearances, excessive cleaeances will produce noises.

sounds like your fan clutch may be failing, remove the drive belt and manually spin all the pulleys by have listen for noise and feel for looseness in the bearings

I may be missing something but i cant see what amp you have? Is it a valve or solid state marshall?

Squealing is a bad wash motor- it will need replacing. Nothing is blocked here.

Asker's Testimonial " This should give me an ida of what to look for once I open er up " -

Run 12V directly to the motor and see if it will run, if it dosent than the motor is bad, if it does than the resister is bad, the resister makes the blower run and also regulates the speeds for the blower, but chanses are if it was making a high pitch squeel before it quit the motor went out.

it sounds like a drive belt to me,, its that or a bearing thats a bit dry,,,check the timeing belts are tight and not polished,,,

Have your egr valvle checked, if not operating properly it can cause engine 'pinging' which sounds like what u are describing. Let me know how it goes. countrycurt0
